Kort presentation
Min forskning fokuserar på att analysera data från internet. Jag är både intresserad av att utveckla nya tekniker för att analysera data och att göra faktiska analyser som baseras på riktig data. Jag har kommit att rikta in min forskning på att analysera förekomsten och innehållet i våldsbejakande extremistiska budskap i digitala miljöer, att utveckla teknik och metod för att göra hot- och riskbedömningar i digitala miljöer samt att upptäcka hat och hot.
